FOUNTAIN-TOOTHIBRUSH.

Application filed February 9', 1918.

To all whom it may concern:

Be it known that I, JASON T. COOK, a citizen of the United States,residing at Astoria, in the county of Clatsop and State of Oregon, haveinvented certain new and useful Improvements. in Fountain- Toothbrushes,of which the following is a specification.

My invention relates to a fountain brush and the improvementsparticularly apply to a tooth brush.

The invention aims to provide a novel, improved and simplifiedconstruction of brush of this nature and particularly one which has ameans to force the cleaning material to the brush head; one having aninsert opening for said material adapted to receive a nozzle of an airbulb to close the opening and to fasten the bulb and its frame to thebrush; and having an improved form of valve means to control the escapeof the material to the brush head; one having a handle provided with achamberto contain the material and with a valve and air bulb in suchrelation therewith that they may be operated by the same hand whichgrasps the handle, and a brush of this nature which may be used as anordinary tooth brush at desired times regardless of the provision of thefountain feature.

With the above and additional objects, such as will hereinafter appear,in View, the invention has been embodied in one preferred form ashereinafter described in connection with accompanying drawingsillustrating the same and wherein:

Figure 1 is a top or plan view of a brush embodying my improvements;

Fig. 2 is a side elevation of the brush;

Fig. 3 is a horizontal sectional view through the brush Fig. 4 is avertical sectional view through the improved brush, and v Fig. 5 is anenlarged detail cross sectional view taken on the line-5-5 of Fig. 2.

Referring specifically to the drawings, wherein like referencecharacters designate like or corresponding parts, a brush is shownhaving a headtl from which bristles 7 extend and which head, is acontinuation of a handle 8. This type of brush is tobe taken asconventional since the improvementsap ply to brushes generally althoughthey are particularly adapted for tooth brushes of which the brush 68 isone type. Handle 8'is hollow so as to have a chamber 9 adaptedSpecification of Letters Patent.

to contain a suitable supply of polishing or cleaning material for theteeth, either in a liquid or powdered form. From the chamber 9 an outletway 10 extends, being pro- .vided partly in the handle and partly in thehead and terminating in an opening 11 in the head centrally of thebristles 7.

A suitable valve 12 is provided to control the outlet or escape ofmaterial from the chamber 9. A chamber 13 is provided transversely ofthe handle 8 and said valve 12 is slidably mounted therein. A fasteningplate 14 is countersunk in and fastened to thehandle 8 in any suitableway or manner. Valve 12 is slidable transversely of the brush andlongitudinally of the chamber 13 and has an abutment wall or shoulder at15 adapted to engage the inner face of the plate 14 to preventdisplacement of the valve 13. From the Wall 15, a reduced shank 16extends, passing through the plate 14 and beyond it havinga head 17. Thevalve and plate are so constructed that they may be connected with theshank 16 extending through an opening in the plate. A way 18 extendscompletely through the valve 12 and is normally held ol'it of alinementwith the way 10 by means of an expansion spring 19 within the chamber 13hearing against one wall at the chamber and against the inner end of thevalve. This spring normally maintains shoulder 15 in contact with theplate 12 and the head 17 spaced from the plate 14. Thus the head may bepressed inwardly against the tension of spring 19 so as to aline theways 18 and 10.

From the construction described, it will be realized that when aquantity of the cleaning or polishing material is desired on thebristles or tufts 7, the operator with the same hand which grasps handle8, pushes the head 17 inwardly alining the ways 10 and 18 so that thematerial may pass therethrough and escape at the openmg 11 onto thebristles or tufts. After the desired quantity has escaped, the fingerenusually but when the owner desires to travel of the cleaning orpolishing material in the chamber 9.

Chamber 9 is filled with the Cleaning o'r polishing material through theopenings at one end of the handle. This opening is designated 20' and isnormally closed by a nipple 21 which engages screw threads projectinginto the opening 20. Nipple 21 leads from a compressible air bulb 22.This bulb 22 is preferably surrounded by a guard frame 23 through whichthe nipple 21 extends and to which it is preferably screwthreaded orotherwise rigidly connected.

When the ways 10 andv 18 are in alineinent; bulb 12 may be compressed soas to expel air through the nozzle or nipple 21 into the chamber 9 toforce the cleaning or polishing material therefrom through the ways 10and 18 to the brush head. It is to be particularly noted that the bulb22 and the valve l2 are so disposed that the same' hand of the operatorwhich grasps the handle 8 may also operate the valve and the bulb. I

Since merely the preferred embodiment of the invention has beenillustrated and described, it is to be understood that changes in thedetails of construction may be resorted to without departing from thespirit and scope thereof as defined by appended claim.

I claim: 4 r A. fountain brush consisting of a head equipped with ahandle provided with a longitudinal cavity communicating with the baseof the tufts 0f the head, a portion of the handle remote from that partin which the cavity is formed, being removable and open from to tobottom, a compressible bulb mounte said detachable head and housedcompletely within the plane of'the latter, said bulb communicating withthe cavity in .the handle to eject the contents of they latter into thetufts of the brush.

In testimony whereof I afiix my signature in presence of two witnesses;v
